### Graphics in Turing

Variables that do not have to be declared that give you the maximum value for your x and y co-ordinates.

(maxx,maxy)

(0,maxy)

(0,0)

(maxx,0)

What are maxx and maxy?
• They will be whatever you set them at
• DEFAULTS
• Maxx 639
• Maxy399
• ---
• setscreen ("graphics:max;max,nobuttonbar")
• Setscreen (“nocursor”)turns off input cursor
• Setscreen (“noecho”)does not show letters as you type

Drawfill

Used for triangles and other odd shapes that you make. This will let you colour them in.
